Device in BOOTSEL cant be seen

[gusisin]

My device mounts in BOOTSEL and shows the file system but pico tool reports `pi@raspberrypi:~/pico/picotool $ picotool info --bus 1 --address 21 No accessible RP2040 device in BOOTSEL mode was found at bus 1, address 21.

but:

Device at bus 1, address 21 appears to be a RP2040 device in BOOTSEL mode, but picotool was unable to connect`

environment: Built following getting started guide Linux raspberrypi 5.10.52-v7l+ #1441 SMP Tue Aug 3 18:11:56 BST 2021 armv7l GNU/Linux pico connected via USB

Have you tried using sudo ?

[Sukruthi-C]

How did you fix this?

@Sukruthi-C See the section in https://github.com/raspberrypi/picotool/blob/master/README.md about udev rules. Alternatively, run picotool with sudo, as I mentioned above.

@danergo You should probably ask for help on the Adafruit forums.

Thank you! It turned out this was caused by a bad driver. :) Correct one is "WinUSB (v6.1.7600.16385)" as of now.
